anyone knows which workshop around KL or selangor that can remove rust on roof? i know some wira owner faces the same problem as mine. pls dont advice me to change to a new or 2nd hand rooftop as some ppl did. i know thats the best solution but its too expensive laaa. if anyone know any workshop that can do this kind of work n can give gurantee that rust wont come out again, pls do let me know exact location n also the name of the workshop.
